Abstract

The invention discloses a silver / silver chloride electrode material and a method for manufacturing the same. The electrode material comprises, by weight, 15%-70% of silver / silver chloride powder, 1%-15% of adhesion agents and 15%-70% of alcohol and ethers diluents. The method for manufacturing the electrode material includes firstly, manufacturing the silver / silver chloride powder; secondly, adding the adhesion agents and the alcohol and ethers diluents into the silver / silver chloride powder to mix the adhesion agents, the alcohol and ethers diluents with the silver / silver chloride powder to obtain a mixture; and thirdly, mechanically grinding the mixture to obtain slurry with certain consistence for standby application. The silver / silver chloride electrode material and the method have the advantages that the adding proportion of the adhesion agents to the diluents is controlled, so that the inky or pasty silver / silver chloride slurry can be manufactured, has a high-dispersion electrochemical interface and is convenient to process, and a silver / silver chloride electrode which can meet different requirements can be manufactured by a process for coating the slurry on a substrate and molding at low pressure or hand pressure.

Description

technical field

[0001] The invention relates to a silver / silver chloride electrode material, a preparation method and an electrode. Background technique

[0002] Silver / silver chloride (Ag / AgCl) electrode is a common reference electrode, which has the advantages of high exchange current density, low polarization, low impedance, and constant potential. Because it can accurately detect bioelectrical signals, the Ag / AgCl electrode is a relatively mature bioelectrical recording electrode in practical applications, and has been widely used in EEG, EMG, ECG, etc. Traditional Ag / AgCl electrodes are manufactured by several methods, namely (a) electrochemically treating silver to chlorinate the surface to form a thin layer of silver chloride, (b) pressing silver and silver chloride particles to form Ag / AgCl AgCl disc electrodes, and (c) coating of Ag / AgCl conductive ink on the dielectric substrate.

[0003] The excellent electrode performance of silver / silver chloride depends ...
